Now have two, both problem free - Bushnell Rimfire Optics 6-18x40mm Side Focus Rifle Scope

Took a chance with one and it was more than I expected. Tracks very well, clear glass, focus is smooth but nor sloppy, with excellent parallax adjustment. Fine adjust the focus to get parallax free even with nearly an inch or so head movement. Used from a bench at 25 to 100yds with same results. first scope is on a 10/22 that is actually without any Ruger parts. a custom build that shoots 3/4 MOA from a bench. Consistently. A second Ruger build now is topped off with another 6-18x40. With Bushnell announcing the discontinuance of this scope I am getting another. I consider it to be a great bargain for what it costs. I suspect a lot of the not so good reviews on the net about this scope are due to poorly manufactured rings stressing the tube and thus the erector. I have never had an issue with Leupold rings, other 'Name Brands' not a perfect record with me. If the 'Planet' gets more 6-18x40's Rimfires in don't hesitate. Verified Owner from WV
